By way of example, and referring to FIG. 1 and FIG. 2, one embodiment of system 100 comprises left central hub 1A is rotationally coupled to left push handle 2A, left front leg 3A and left rear leg 4A. Left front leg 3A extends downward and terminates in left front wheel 5A. Left rear leg 4A extends downward and terminates in left rear wheel 6A.

Likewise, right central hub 1B is rotationally coupled to right push handle 2B, right front leg 3B and right rear leg 4B. Right front leg 3B extends downward and terminates in right front wheel 5B. Right rear leg 4B extends downward and terminates in right rear wheel 6B. Left front leg 3B is mechanically coupled to foot rest 14 which is further mechanically coupled to right front leg 3B. Additionally, left rear leg 4B is mechanically coupled to rear lower horizontal support 27 which is further mechanically coupled to right rear leg 4B. Left rear wheel 6A and right rear wheel 6B can be locked to prevent the system from rolling.

Left push handle 2A is rotationally coupled to left swing arm 24A with a left fastener 25A. Likewise, right push handle 2B is rotationally coupled to right swing arm 24B with a right fastener 25B. Left swing arm 24A and right swing arm 24B are mechanically coupled to handle support 26 with fasteners 25A, B.

As shown in more detail in FIG. 6, left front leg 3A is rotationally coupled to left front swing arm 20AA with left front upper fastener 20A. Left front swing arm 20AA is mechanically coupled to left front upper fastener 20A which rests inside left slide cut out 21A on left seat support 19A. Left seat support 19A is rotationally coupled to left rear swing arm 22A with fastener 22AB. Left rear swing arm 22A is further rotationally coupled to left rear leg 4A with fastener 22AA.

Similarly, as shown in FIG. 10, right front leg 3B is rotationally coupled to right front swing arm 20BA with right front upper fastener 20B. Right front swing arm 20BA is mechanically coupled to right front upper fastener 20B which rests inside right slide cut out 21B on right seat support 19B. Right seat support 19B is rotationally coupled to right rear swing arm 22B with fastener 22BB. Right rear swing arm 22B is further rotationally coupled to right rear leg 4B with fastener 22BA. Left seat support 19A is mechanically coupled to right seat support 19B by seat horizontal support 18.

Left central hub 1A is mechanically coupled to left adjustable strap 11A. Left adjustable strap 11A, having left adjuster 12AA, is further attached to left cushioned strap 10A. Left cushioned strap 10A is attached to left cushioned push handle 9A. Left push handle grip 9A covers a portion of left push handle 2A. Similarly, right central hub 1B is mechanically coupled to right adjustable strap 11B. Right adjustable strap 11B, having right adjuster, is further attached to right cushioned strap 10B. Right cushioned strap 10B is attached to right cushioned push handle 9B. Right push handle grip 9B covers a portion of right push handle 2B.

Left push handle 2A and right push handle 2B are mechanically coupled to backrest 13 by attachments 17. Backrest 13 is further mechanically coupled to upper compartment bag 8 and safety strap 15. Backrest 13 is further mechanically coupled to seat 7.

Turning to FIGS. 3A-3D, upper compartment bag 8 comprises smaller compartment bag 28. Smaller compartment bag 28 is connected to left cylindrical shaped compartment 32 and right cylindrical shaped compartment 32. Smaller compartment 28 is configured to accommodate handy wipes, diapers, or snacks. Cylindrical shaped compartment 32 can accommodate drinks. Upper compartment bag 8 is attached to upper compartment bag button strap 30 that can be used to close the stroller into a backpack as shown. Seat 7 is mechanically coupled to sectional pieces 29 wherein sectional pieces 29 can house foam cushions for the seat and backpack. Seat 7 is further mechanically coupled to seat button strap 31. Holistically, all of the material that could possibly be stored in any of these compartments is called “equipment.”

To fold system 100 into a backpack from a stroller, a user rotates left front leg 3A about left central hub 1A until left front leg 3A is parallel to left push handle 2A. The user then rotates right front leg 3B about right central hub 1B until right front leg 3B is parallel to right push handle 2B. The user then rotates left rear leg 4A about left central hub 1A until left rear leg 4A is parallel to left push handle 2A. The user then rotates right rear leg 4B about right central hub 1B until right rear leg 4B is parallel to right push handle 2B. Finally, as shown in FIG. 4 and FIG. 5, the user joins upper compartment bag button strap 30 to seat button strap 31.

One of the unique features of the present invention which facilitates such simple folding is central hub 1 which is shown in more detail in FIG. 7, FIG. 8 and FIG. 9. Central Hub 1 is responsible for the manipulation of the stroller/sports seat from stroller/sports seat to backpack configurations. Central hub 1 comprises central axis nut 36. Central axis nut 36 slides through front lock 37. Front lock 37 is immediately adjacent to outer arm 38. Outer arm 38 can fit inside and partially rotate in an outer slot on hub assembly 35. Likewise, inner arm 40 can fit inside and partially rotate in an outer slot on hub assembly 35. Inner arm 40 is immediately adjacent to an inner retainer ring 39 and an outer retainer ring 39. Retainer rings 39 hold inner arm 40 in place while allowing hub assembly 35 and outer arm 38 to freely rotate. Inner arm 40 is immediately adjacent to spring 41. Spring 41 place tension against the components to push the male components into the female components to maintain positive pressure in locking positions of the pieces of central hub 1. Spring 41 is immediately adjacent to rear lock 42. Rear lock 42 is immediately adjacent to cap 43. Cap 43 can be threaded onto central axis nut 36 to hold the central hub components together.

To use central hub 1, front leg 3 can be attached to outer arm 38. Push handle 2 can be attached to hub assembly 35. Rear leg 4 can be attached to inner arm 40. Hub assembly 35 is configured such that outer arm 38 can rotate from and be locked into an open position, which is useful when system 100 is used as a stroller. Outer arm 38 can be pressed into a channel from the open position and rotated into a closed position which is useful when system 100 is used as a backpack. Hub assembly 35 is further configured such that inner arm 40 can rotate from and be locked into an open position, which is useful when system 100 is used as a stroller. Inner arm 40 can be pressed into a channel from the open position and rotated into a closed position which is useful when system 100 is used as a backpack.

Persons of ordinary skill in the art may appreciate that numerous design configurations may be possible to enjoy the functional benefits of the inventive systems. Thus, given the wide variety of configurations and arrangements of embodiments of the present invention the scope of the invention is reflected by the breadth of the claims below rather than narrowed by the embodiments described above.
